Surgical drape

Abstract

The invention concerns a novel surgical drape with a first fenestration for an incise film and a collection pouch related to this film for surgical residues according to the state of the art. The drape features at least one further fenestration for the reception of a cover for a reference device protruding from the level of the surface of the drape, which is identifiable for a 2- or 3-dimensional measurement system.

1 . Surgical drape for covering operating sites on a body of a patient comprising:
 a top and bottom surface;   a first fenestration in the drape, the first fenestration covered by an incise film aligned with the top surface of the drape;   a second fenestration in the drape spaced from the first fenestration and defining a perimeter;   a means of cover firmly bound along the entire perimeter of the second fenestration, the means of cover having an elongated form which extends upwardly from the top surface of the surgical drape and terminates in a closed upper end, the means of cover including a transparent portion, the transparent portion spaced from the top surface of the surgical drape to permit transmission of radiation by a measurement system to be used in conjunction with a means of reference.   
     
     
         2 . Drape according to  claim 1 , characterized by the fact that the means of cover is made of a flexible material. 
     
     
         3 . Drape according to  claim 1 , characterized by the fact that the means of cover features along the surface between the drape and the upper end at least one means of reduction, for the reduction of the perimeter of the means of cover. 
     
     
         4 . Drape according to  claim 1 , characterized by the fact that the means of cover features at least one means of reduction along the surface between the drape and the closed upper end for the reduction of the length of the means of cover, so that the closed upper end can also be stretched firmly and smoothly over the means of reference, whereby creases or other distortions of the radiation of the measurement system falling on the means of reference or reflected therefrom are avoided. 
     
     
         5 . Drape according to  claim 5 , characterized by the fact that the means of reduction are realized in the form of removable adhesive strips or simple cords. 
     
     
         6 . Drape according to  claim 1 , characterized by the fact that the means of cover features pre-shaped moldings on an upper, drape-opposing end for the reception of shapes of the means of reference. 
     
     
         7 . Drape according to  claim 1 , characterized by the fact that the means of cover is realized to be able to be sterilized. 
     
     
         8 . Drape according to  claim 1 , characterized by the fact that the drape is realized attached firmly to the means of cover along the fenestration by the technology of ultrasonic welding, adhesion or heat welding. 
     
     
         9 . Drape according to  claim 1 , characterized by the fact that the means of cover is realized with an elastic or plastic material and in the area of the coverage of the means of reference is inflatable so that formation of creases that would distort the radiation directed to or reflected from the means of reference are avoided. 
     
     
         10 . Drape according to  claim 1 , further comprising at least two second fenestrations and at least two means of cover, one means of cover for each second fenestration. 
     
     
         11 . Drape according to  claim 1 , wherein the means of cover, measured from the middle point of the fenestration surface at the foot of the means of cover, feature a distance of 10 to 100 cm from the center of the incise film. 
     
     
         12 . Drape according to patent  claim 10 , characterized by the fact that one of the at least two means of cover, respectively, are arranged at a distance of approx. 40 cm left and right in a perpendicular distance from the center of the incise film, so that during an operation, swinging the means of reference from one side to the other can be easily undertaken. 
     
     
         13 . Drape of  claim 2 , wherein the flexible material is a polymer. 
     
     
         14 . Drape of  claim 7 , wherein the means of cover can be sterilized with gamma radiation or hot steam. 
     
     
         15 . Drape of  claim 1 , wherein the means of cover is firmly bound to the top surface of the drape. 
     
     
         16 . Drape of  claim 10 , wherein the at least two means of cover have a minimum outside diameter of 10-50 cm. 
     
     
         17 . Drape according to  claim 11 , wherein the distance is 50 cm from the center of the incise film. 
     
     
         18 . Drape according to  claim 1 , wherein the means of cover is a different material than the material of the incise film covering the first fenestration. 
     
     
         19 . Drape according to  claim 1 , wherein a bottom portion of the cover comprises a material that is stiffer than an upper end portion of the cover.
